Code P0353 Hyundai Description

The P0353 diagnostic trouble code for Hyundai vehicles indicates a problem with the ignition coil 'C' primary/secondary circuit. The ignition coil is a crucial component of the ignition system that converts the low voltage from the battery into the high voltage needed to ignite the fuel-air mixture in the engine cylinders. The primary circuit is responsible for delivering the low voltage signal to the ignition coil, while the secondary circuit amplifies this signal to produce a spark at the spark plug.
